| i was thinking about making another gun to compliment my 5.56. and i limited it down to the .308 or the 6.8 SPC. this gun will be for recreational shooting mainly. and one of my nephews like to go to the range with me, hes 12 so i want something with manageable recoil for him. i no the .308 has a lot more recoil then the 5.56. so just wondering, compared to a 5.56, how the 6.8 recoil is? |

6.8SPC recoil is similar to 762x39 Russian, not much, and with a muzzle brake, even less.
You can buy a 6.8 upper and use your exsisting 5.56 lower. .308 requires a whole new rifle. brass is kinda pricey, but it uses 90-130gr .270 bullets that are availible at any decent gunstore. I like H322 powder Make sure you get a 1:11 or 1:12 twist, not 1:9 or 1:10. and get the newer SPCII/spec2 chamber |

i did some looking around and idk if i was reading right, but what i read it that the 6.8 was pretty susceptible to wind drift compared to the 5.56 and the 7.62. is that true?
also so i can just throw a 6.8 upper on top of my 5.56 lower? i new the .308 was a bigger upper so i would have t get a new lower for it. |

Quoted:
I have a "heavy ass" 8 oz. buffer made by Spikes Tactical in my 6.8 SPC and I swear that thing has "much less" recoil than any of 5.56's.

Wind drift versus a 5.56? Are you kidding? And yes, you can throw a 6.8 upper on a 5.56 lower, I did that with my first build. You will need 6.8 mags though. Jim |

Recoil: If 5.56 is a 1 and 308 a 10, IMO is that 6.8 is a 2. Hardly worth talking about when compared to 5.56.
I don't have a BC chart in front of me, but the 110 grain 6.8 is a bit better than typical loads in either 5.56 or 7.62x39 IIRC - not that any of them are that great when compared to typical hunting loads (let alone match) out of typical hunting calibers... |

Quoted: That handguard in tan is really growing on me. I'll second the "Nice done sir" comment.Quoted: I have a "heavy ass" 8 oz. buffer made by Spikes Tactical in my 6.8 SPC and I swear that thing has "much less" recoil than any of 5.56's.
